The Use of Rattan Processed Waste as A Complement in Fiber Concrete

Abstract

In this research, the fiber is natural fiber from rattan. Considering, Central Kalimantan Province is home for the commodity of rattan handicraft. Then, the rattan processed waste is used as fiber in concrete. The percentages were 0.1%; 0.3%; and 0.5%, based on the cement needs. The particular study aimed to provide information about rattan fibers if used in concrete mixtures, find out the compression strength after the addition of rattan processed waste fibers, and the ratio occurs after the addition of rattan processed waste fibers. The research stages were material preparation and checking, making the specimens, immersion of test specimens, compression strength test and analysis, and conclusion. The results found out the mean of compression strength in concrete with a mixture type without fiber of 391.378 kg cm-2, while in the mixture type 0.1% at 371.734 kg cm-2, mixed type 0.3% at 308.267 kg cm-2, and mixture type of 0.5% at 297.689 kg cm-2. There was a decrease for each mixed type of 5.02%; 21.24%; and 23.94%, respectively. The more fibers added, the more the compression strength decreases, but the more fiber used, the greater the strength of the concrete in holding cracks.
